We also believe that strong and transparent carbon markets, such as The Voluntary Climate Marketplace (TVCM) powered by TMX Trayport, play a vital role in enhancing global ecosystem health. Neutralizing and Reducing Emissions To offset our 2024 annual reported gross Scope 1, 2, and 3 emissions, we have purchased and retired voluntary carbon offset credits through TVCM, a practice we have maintained since fiscal year 2020. We select carbon offsets from verified, credible, industry-leading registries, prioritizing projects based on their geographical location and the socio-economic benefits they provide. Our intention is to progressively reduce our reliance on carbon offsets by identifying opportunities for emissions reductions as we develop and implement our climate transition plan. All of our major corporate sites in Canada are Leadership in Energy and Environmental Design (LEED®) certified and, as of December 31, 2024, 83% of TMX Group’s total office footprint was LEED® certified or in the process of certification.12 LEED® is the most widely used green building rating system in the world and a globally recognized symbol of sustainability achievement and leadership. LEED® certification has been integrated as a criteria for all future real estate office space as part of TMX’s real estate strategy. Our TMX Trayport London office has the ISO 14001 and ISO 9001:2015 environmental management systems accreditation. 12 We shifted from reporting specific levels of LEED certifications across the properties leased for our office locations due to the challenges associated with ensuring we capture updated data from landlords and in alignment with our criteria for future real estate office space selection.
